" Claims. (Cl. 153-11) "In the cop'ending application of Francis E. Allenon an nEXpansible"Wall Structure, Serial No. 459,987, which was filed in the United States Patent Offlce on October 4,

1954 (now Patent No. 2,862,584, dated December 2,

:1958'), there is" disclosed a metallic building panel made of thin sheet material. This panel is reinforced by a structural member contacting with a surface of the'panel. The member has a pair of lateral flanges that are arcuate in cross-section, and the. outer edges of these flanges con- St'itilte runners that project away from the panel surface. "Moreover, a plurality of clips have'hookhaped ends for .slidably receiving the runners and further'havi'ng feet which are anchored to the panel surface by stirrups.

Each of these clips is L-shaped before being bentinto 1, the'shape of a hook.

As the' cardinal object of my invention, it is proposed to provide a shaping diefor bending theanchor clips over the reinforcing member of the puilding panel shown in the above mentioned copending application. It is pro posed to crimp the hook against the runner with suflicient pressure-so as to hold the reinforcing member firmly in place 'with respect to the building panel.

As a still further object of my invention, it is proposed to ,provide a shaping die of the character described, .rnay be readily secured to the runners of the .,reinforcing. member with ease and facility, and which may.be readily shifted along the length of the reinforc" ing" member after each clip has been crimped.

. Another object is to provide a shaping die of the type set for th, which is simple in construction, durable and eflicient for the purpose intended. i Other objects and advantages will appear as the: specification proceeds. The novel features willbe pointed out inthei claims appended hereunto.

ice 4 Detailed description Referring now to the drawings in detail, I have illus trated a fragmentary portion of a building panel which is indicated generally at A. This panel ismore fully disclosed in the copending application of Francis E. Allen, Serial No. 459,987, mentioned earlier. In its structural features, the panel A defines a front plate 10 having marginal flanges 11 rising from the four sides thereof. This panel is made of thin sheet material, and is reinforced by a structural member designated generally at B which has the cross-sectional shape shown in Figures 3 and 4. g

As shown, the member B defines a web 12 having a pair of lateral flanges 13 projecting from the web. The

lateral flanges are arcuate in cross-section, and the outer edges of these flanges constitute runners 14 that project away from the front plate 10 and eat end longitudinally leg 15 which contacts with the outermost surface of one of the runners, with the base leg 16 of the clip being anchored to the front plate 10 of the panel A by a stirrup 17, the latter being fixed to the front plate 10. As indicated in Figure 1, these clips are arranged at intervals "along the length of the member B.

Initially, the anchor clips C have their base legs I6 inserted into the stirrups 17, with their legs 15 projecting upwardly from the front panel :10. Then thereinforcing member B is inserted into place, with the rounded portions 18 of front plate 10.

The parts thus far described are illustrated in the copending, application of Francis E. Allen, Serial No. 459,987, mentionedabove. Since the member B extends substantially the entire width of the panel A, i.e., between two opposing marginal flanges 11, the upwardlyextending legs 15 must be bent over the runners 14 to provide hooks 19 after the member B has been inserted into place on the panel A. This'problem is solved by providing my shaping die, which is designated generally at D.

In its structural features, the die D includes a pair of to allow them to straddle one of the stirrups 17. These guide plates are adapted to be positioned in substantially upright position, and each has a lower end 20 adapted to .rest on the front plate It of the building panel A. The

two .guide plates E are held apart by spacers 21, which are tubular in form, and through which bolts 22 are passed: i

The lower end 20 of each guide plate'E is fashioned with a notch 23 (see Figures 1, 2 and 3) which is positioned to hook over one of the longitudinally-extending runners 14 at a time. Thus the guide plates 5 are held against lateral movement related to the reinforcing men1- ber B. Of course, the guide plates E may have their notches 23 hooked over either of the runners 14, depending' upon the particular anchor clip C that is to be bent, when forming a book 19.

Moreover, the shaping die D includes a reciprocating die part F, which is mounted between the guideplates E for up and down movement. The die part F i's formed with an inclined toe 24 at its lower end,wh'ich toefis positioned to bear against the upwardly-extending leg the lateral flanges 13 contacting with the 'Figure 4).

, 3 I 15 of an anchor clip C, as indicated in Figure 3, when the die part F is moved downwardly.

It will be noted that coacting means designated generally at G is arranged between the guide plates E and the reciprocating die part F for shifting the latter toward the reinforcing member B and into a position whereby the inclined toe 24 will bend theupwardly-extending leg 15 of the clip C, over the runner 14, when the die part F is moved downwardly (see dot-dash line position of the leg 15 in Figure 3). The coacting means G is provided by a slot 25 formed in each of the guide plates E and a transverse pin 26, the latter being carried by the die part F and having its ends projecting through the slots 25. Each slot 25 has upper and lower portions 25a and 2512, respectively. The slot portions 25a and 25b are offset with respect to each other and are interconnected by an inclined slot portion 25c. The transverse pin 26 is secured to the die part F by means of a set-screw 27 or other suitable fastening means (see Figure 4). As the die part F is lowered or raised, the pin 26 must follow the slots 25.

, With particular reference to Figure 2, it will be seen that the transverse pin 26 is disposed at the top of the upper slot portions 25a when the die part F is fully raised. In Figure 3, the pin 26 has been shown as having entered the inclined slot portions 25c; and it will be apparent that further dovmward movement of the die part F will result in bending the leg 15 of the clip C to the left, as suggested by the dot-dash lines. The lower end of the die part F has a restricted notch 28 extending upwardly thereinto, which notch is positioned and dimensioned to crimp the bent leg 15 of the clip C into the hook 19, when the transverse pin 26 moves downwardly into the lower portions 25b of the slots 25, as disclosed in Figure 4. The hooks 19 engage with the runners 14 under pressure, and thus the hooks firmly contact with the runners to hold the reinforcing member B in place relative to the building panel A. I

Obviously, after each anchor clip C has been bent over the runner 14, the shaping die D may be shifted to a new position so that another anchor clip C may be bent into a hook. This process is continued until all of the clips C are bent over the runners 14.

The building panels A are coated with porcelain enamel on their interior and exterior surfaces, as indicated by 29 in both Figures 3 and 4. In order to prevent the enamel from being damaged, it is important that the lower end 30 of the die part F be prevented from striking the front plate 10. For this reason, the lower portions 25b of the slots 25 in the guide plates E terminate at points so that the transverse pin 26 will limit the downward travel of the die part F so that the latter will not strike the front panel 10, as clearly shown in Figure 4.

The reciprocating die part F has an upwardly extending bar 31 fixed thereto, and this bar has an elongated slot 32 formed therein. One of the spacers 21 and its bolt 22 pass through this slot so as to guide the bar 31 in its up and down movement. In order to actuate the bar 31 and the die part F, I have provided a pneumatic ram H, although other suitable means could be provided. As shown in the drawings, this ram is carried by a supporting frame designated generally at J.

- In its structural details, the supporting frame I has a lower horizontal bar 33, which is secured to the tops of the two guide plates E by countersunk screws 34 (see This bar has a pair of rods 35 fastened thereto so as to extend upwardly therefrom (see Figures 1 and 2). The tops of these rods have an upper horizontal bar 36 secured thereto. The bars 33 and 36, together with the rods 35, constitute the supporting frame I.

The pneumatic ram H includes a cylinder 37, which has a bracket 38 fixed to its top. This bracket is secured to a clevis 39 by a journal pin 40, the clevis in 4 i turn being fastened to the upper horizontal bar 36. A piston 41 is mounted in the cylinder 37 and has a piston rod 42 fastened thereto, which projects downwardly through the bottom of the cylinder. The lower end of the piston rod 42 is provided with a clevis 43, which is fastened to the upper end of the bar 31 by a journal pin 44. The bar 31 passes through a notch 45 formed in the bar 33 (see Figures 1 and 3).

It will be obvious that when air is admitted under pressure through a top hose 46 into the upper part of the cylinder 37, the piston 41 will be forced downwardly. At the same time, any air in the cylinder below the piston may be exhausted through a lower hose 47 that communicates with the lower part of the cylinder. This will result in forcing the die part F downwardly toward the building panel A, causing the inclined toe 24 and the re stricted notch 28 to form the hook 19 on the clip C, with the book being 'crirnped over the adjacent runner 14. Conversely, by admitted air under pressure into the lower part of the cylinder through the lower hose 47, and exhausting air from the top of the cylinder through the top hose 46, will result in lifting the die part F. Of course, any suitable control valve may be used for controlling the admission and'withdrawal of the air to and from the cylinder.

For the purpose of permitting the shaping die D to be moved from place to place, when crimping the anchor clips C over the runners 14, a chain 48 has been attached to the upper bar 36. This chain may extend upwardly toward the ceiling of the building (not shown) and over a, pulley, with the opposite end of the chain being counterbalanced. Thus the operator can move the shaping die along the length of the runners 14, with the die D coming to rest each time a clip C is being bent over the runner. Likewise, the shaping die D may be readily shifted from one of the runners 14 to the other.

Summary of operation Having thus described the various details of my shaping die for bending anchor clips over a reinforcing member of a building panel, the operation thereof is summarized briefly as follows:

Assuming that one of the building panels A is arranged on a supporting surface K, and that a plurality of anchor clips C have their base legs 16 secured to the front plate 10 of the panel with their legs 15 extending upwardly, and that the reinforcing member B has been inserted into place between the two rows of anchor clips, as shown in Figures 1 and 3, the operator proceeds as follows:

Initially, the supporting frame I should be lowered toward the panel A so that the notches 23 in the pair of guide plates B will be hooked over one of the upwardlyextending runners 14, as shown in Figures 2 and 3. At this time, the guide plates B should straddle one of the stirrups 17 and its clip C, as disclosed in Figure 1.

As the next step, air should be admitted through the top hose 46 to the interior of the cylinder 37 so as to drive the piston 41 downwardly. At the same time, air should be exhausted from the bottom of the cylinder through the lower hose 47. This will cause the piston rod 42 to force the die part F downwardly. As the transverse pin 26 passes from the upper slot portions 25a into the inclined slot portions 250, the inclined toe 24 will bear against the top of the upwardly-extending leg '15 of the anchor clip C, as clearly shown in Figure 3.

This will cause the toe 24 to bend the leg 15 toward the reinforcing member B, as suggested by the dot-dash lines in Figure 3. As the die part F continues downwardly, the transverse pin 26 will enter the lower slot portions 25c, and this will bring the restricted slot 28 in the lower part of the die part F directly in alignment with the runner 14 over which the leg 15 is being bent. Further downwardly movement of the die part F will cause the restricted slot 28 to form the leg 15 into the hook 19, with the latter firmly engaging with the runner 14. However, the lower end 30 of the die part F will stop short of the front plate 19, due to the pin 26 contacting with the lower ends of the slot portions 25b. This will preclude the die part F from striking and damaging the layers 29 of the porcelain enamel.

Now the air may be exhausted from the upper part of the cylinder 37 through the top hose 46, and at the same time air may be admitted under pressure into the lower part of the cylinder through the lower hose 47. This will raise the die part F to its starting position, as shown in Figure 2. These operations are repeated until all of the anchor clips C are bent over the runners 14 on both lateral sides of the reinforcing member B. The counterbalanced chain 48 will permit the supporting frame I to be shifted readily from place to place.
